  • Page 19: Sequential Function

    #Pizza Hut Make Table operating and service manual Sequencial functions 1) POWER ON (BOTH COMPARTMENTS NEED COOLING) CONTROLLER B CONTROLLER A As soon as Pan and Counter Compartments start asking cooling to the system (in the instance that the inner temperatures are higher than the set point), there is 1 minute delay during which the cooling LED will blink.
  • Page 20 #Pizza Hut Make Table operating and service manual 2) RUNNING CONFIGURATION AFTER 1° MINUTE DELAY Assuming that temperatures in both compartments are higher than the set point, both A and B valves will open to circulate refrigerant in the respective cooling circuits. Opening the two valves will increase the suction pressure above 0 bar + differential, thus allowing the pressure switch to close the circuit and engage compressor.

  • Page 23 #Pizza Hut Make Table operating and service manual 5) BOTH COMPARTMENTS HAVE REACHED THE SET POINT TEMPERATURE Both solenoid valves will close. Compressor will still run in a “pump-down” configuration, sucking the entire refrigerant from the evaporating circuits and pushing it into the liquid receiver.
  • Page 24 #Pizza Hut Make Table operating and service manual 6) PRESSURE SWITCH OPENS As the compressor is still running while valves A and B are closed, the suction pressure will gradually decrease until reaching to 0.10 PSI, thus causing the pressure switch to open and cut off both compressor and condenser fan.
